Bacterial growth methods

(a) Bacteria can be grown in a liquid medium inoculated with cells from another culture. In liquid, dense growth occurs making the medium appear cloudy. (b) Bacteria can be grown on a plate of semisolid growth medium on which a few drops of a dilute bacterial-cell solution have been spread. On the semisolid medium, bacteria grow as colonies(a) Bacteria can be grown in a liquid medium inoculated with cells from another culture.
